Key to happy thoughts

Some people say happiness is subjective. While for some people happiness is materialistic pleasures, for others happiness means inner peace and tranquility. Some people chase materialistic things for happiness such as money, property and substances, but others wander about seeking inner peace. While there may be differences in the meaning of happiness, everyone would agree that the key to true happiness is happy thoughts. When a person is happy inside, it reflects in his personality. The key to happy thoughts is to maintain a positive attitude towards the people around you and keeping your calm in all situations. If a person manages to do away or at least control the vices in him such as fear, anger, jealousy etc he can be happy and can make people around him happy. What say, friends?
